IoT Edge Computing with MicroK8s

By: Karthikeyan Shanmugam

Overview of this book

Are you facing challenges with developing, deploying, monitoring, clustering, storing, securing, and managing Kubernetes in production environments as you're not familiar with infrastructure technologies? MicroK8s - a zero-ops, lightweight, and CNCF-compliant Kubernetes with a small footprint is the apt solution for you. This book gets you up and running with production-grade, highly available (HA) Kubernetes clusters on MicroK8s using best practices and examples based on IoT and edge computing. Beginning with an introduction to Kubernetes, MicroK8s, and IoT and edge computing architectures, this book shows you how to install, deploy sample apps, and enable add-ons (like DNS and dashboard) on the MicroK8s platform. You’ll work with multi-node Kubernetes clusters on Raspberry Pi and networking plugins (such as Calico and Cilium) and implement service mesh, load balancing with MetalLB and Ingress, and AI/ML workloads on MicroK8s. You’ll also understand how to secure containers, monitor infrastructure and apps with Prometheus, Grafana, and the ELK stack, manage storage replication with OpenEBS, resist component failure using a HA cluster, and more, as well as take a sneak peek into future trends. By the end of this book, you’ll be able to use MicroK8 to build and implement scenarios for IoT and edge computing workloads in a production environment.

Part 3: Running Applications on MicroK8s

This part focuses on the implementation aspects that are common for any IoT/edge computing applications, such as running your applications on a multi-node Raspberry Pi cluster, installing/configuring different CNI plugins for network connectivity, configuring load balancing, configuring logging, monitoring, alerting options, building, and deploying machine learning models, and serverless applications.

This part of the book comprises the following chapters:

  • Chapter 5, Creating and Implementing Updates on Multi-Node Raspberry Pi Kubernetes Clusters
  • Chapter 6, Configuring Connectivity for Containers
  • Chapter 7, Setting Up MetalLB and Ingress for Load Balancing
  • Chapter 8, Monitoring the Health of Infrastructure and Applications
  • Chapter 9, Using Kubeflow to Run AI/MLOps Workloads
  • Chapter 10, Going Serverless with Knative and OpenFaaS Frameworks
